Swift 5, works for iOS12, iOS13 and iOS14

  func tableView(_ tableView: UITableView, willBeginEditingRowAt indexPath: IndexPath) {
    // for iOS13, iOS14
    if let swipeContainerView = tableView.subviews.first(where: { String(describing: type(of: $0)) == "_UITableViewCellSwipeContainerView" }) {
      if let swipeActionPullView = swipeContainerView.subviews.first, String(describing: type(of: swipeActionPullView)) == "UISwipeActionPullView" {
        swipeActionPullView.frame.size.height -= 10
      }
    }

    // for iOS12
    tableView.subviews.forEach { subview in
      if String(describing: type(of: subview)) == "UISwipeActionPullView" {
        subview.frame.size.height -= 10
      }
    }
  }
